Description
Virtual machine I created does not receive interrupt from pci attached hardware. I met with the same problem in past using a real machine, that time was a bios defect solved by simply updating the bios version.

the hardware I currently using supports IOMMU which is active and running.

The mainboard I'm using has just two non shared interrupts slot, I tried them both with the same results, no interrupts.
